I required some parts and 6 hours of labor @$75 per...he invoiced me for $600 in parts and 26 hours labor!!! I offered twice the original agreement and he worked the situation like a pro, locking the front gate to prevent me from leaving!! I called 911 and three Lewisville Police Officers arrived and demanded he open the front gate. Then the Police proceeded to question the scumbag on why his invoice kept changing in regards to the amount. The police were very understanding and helped me to obtain a total price for repairs which was more in line with the work performed...I still payed more than the agreed price.
